簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 62 - 77; 臀鰭軟條: 52 - 57. Diagnosis: long and narrow, "knife-shaped" frontal fontanel (Ref. 248, 81644), 2.5-3.0 times as long as wide (Ref. 81644). Tooth plates remarkably broad; median vomerine tooth plate length strikingly shorter than premaxillary length (Ref. 248). Vomerine tooth band very short, length 2.0-5.0% HL (mean 3.3), clearly shorter than premaxillary tooth band (Ref. 81644). Head rectangular in dorsal outline (Ref. 248), relatively large (HL 25.3-27.6% SL, mean 26.4) and wide (width 18.6-20.9% SL, mean 19.8)(Ref. 81644). Supraorbital and "dermosphenotic" never sutured; reduced suprabranchial organ (Ref. 248). Pectoral spine serrate only along anterior margin; flank neuromasts arranged in a regular pattern; postorbital bones not in contact; eyes laterally positioned, interorbital width 44.5-49.0% HL, mean 47.3; 14-16 rakers on 1st gill arch (Ref. 81644).
Coloration: preserved specimens dark reddish brown on back and flanks; ventrum and lower parts of paired fins pale (Ref. 81644).
特徵為它的刀狀' 額骨囪門與用它的犛骨齒碟長度以平均長度顯著短於上頜骨前的長度。 頭部背面的矩形輪廓。 眶上的與皮蝶骨的' 從不縫合了。 齒板顯著寬。 縮小的鰓前器官了。
Facultative air-breathing (Ref. 126274); Lacustrine species living in deeper as well as in shallow waters (Ref. 248, 78218). Larger specimens feed mainly on fish, especially Cichlidae; small specimens feed on insect larvae, Chironomids-Odonata (Ref. 248, 78218).
更深地被生活於的湖泊種以及在淺水區中。 較大的標本主要捕食魚, 尤其慈鯛科魚類; 小的標本吃昆蟲幼生，寶刀魚-蜻蛉.(參考文獻 248)
